Description

本考案は、パンツタイプの吸収性物品に関する。 The present invention relates to a pants-type absorbent article.

従来より、着用者からの排泄物を受ける吸収性物品の１つとして、上端に胴部開口を有するとともに下部に一対の脚部開口を有するパンツタイプの使い捨ておむつが利用されている。一方、使い捨ておむつでは、少量の排尿時であってもおむつ全体を交換する必要があるため、使用者にとって経済的な負担が大きくなってしまう。そこで、使い捨ておむつの内側において安価な補助吸収具（いわゆる、尿取りパッド等）により着用者の排泄部を覆い、排泄後に補助吸収具のみを交換することが行われている。 Conventionally, a pants-type disposable diaper having a trunk opening at the upper end and a pair of leg openings at the lower part has been used as one of the absorbent articles that receive excrement from the wearer. On the other hand, in a disposable diaper, since it is necessary to replace the entire diaper even when a small amount of urine is discharged, an economic burden increases for the user. Therefore, it has been practiced to cover the excretion part of the wearer with an inexpensive auxiliary absorbent device (so-called urine collecting pad or the like) inside the disposable diaper and replace only the auxiliary absorbent device after excretion.

このような使い捨ておむつでは、補助吸収具を取り付ける際に利用される目印が設けられる場合がある。例えば、特許文献１のパンツ型の使い捨ておむつでは、胴部開口弾性部材と吸収体の上端との間に、使い捨ておむつの外側から視認可能な目印が設けられる。使い捨ておむつおよび補助吸収具が着用者に装着されると、介護者等により、補助吸収具の上端部が使い捨ておむつを介して視認され、目印を基準として補助吸収具の上端部の位置が調整される。 Such a disposable diaper may be provided with a mark used when the auxiliary absorbent is attached. For example, in the pants-type disposable diaper of Patent Document 1, a mark that is visible from the outside of the disposable diaper is provided between the trunk opening elastic member and the upper end of the absorber. When the disposable diaper and the auxiliary absorbent device are attached to the wearer, the upper end portion of the auxiliary absorbent device is visually recognized through the disposable diaper by a caregiver or the like, and the position of the upper end portion of the auxiliary absorbent device is adjusted with reference to the mark. The

一方、特許文献２では、オープンタイプの使い捨ておむつにおいて、トップシートを介して着用者側から視認可能な目印が吸収体に設けられる。当該目印は、使い捨ておむつの着用者側に補助吸収具を取り付ける際の位置決めに利用される。 On the other hand, in patent document 2, in an open-type disposable diaper, a mark visible from the wearer side is provided on the absorbent body via a top sheet. The said mark is utilized for positioning at the time of attaching an auxiliary | assistant absorber to the wearer side of a disposable diaper.

ところで、特許文献１の使い捨ておむつでは、前方部および後方部における目印の上下方向の位置がおよそ等しい。したがって、補助吸収具は使い捨ておむつの長手方向の略中央に取り付けられる。また、着用者の排尿位置は、使い捨ておむつの下端よりも前側であるため、介護施設等において、補助吸収具を使い捨ておむつの前側に偏らせて取り付ける場合もある。 By the way, in the disposable diaper of patent document 1, the position of the up-down direction of the mark in a front part and a back part is substantially equal. Therefore, the auxiliary absorbent is attached to the approximate center in the longitudinal direction of the disposable diaper. Moreover, since a wearer's urination position is a front side rather than the lower end of a disposable diaper, in a nursing care facility etc., an auxiliary | assistant absorber may be biased and attached to the front side of a disposable diaper.

しかしながら、補助吸収具が上述のように取り付けられた場合、着用者が仰向けになった状態で排尿が行われると、尿は重力により使い捨ておむつの後方部へと移動し、後方部からの漏出が発生するおそれがある。 However, when the auxiliary absorbent is attached as described above, if urination is performed with the wearer lying on his back, the urine moves to the rear part of the disposable diaper due to gravity, and leakage from the rear part occurs. May occur.

本考案は、上記課題に鑑みなされたものであり、補助吸収具を使い捨ておむつの後方部に偏らせて取り付けることを容易とすることを目的としている。 This invention is made | formed in view of the said subject, and aims at making it easy to attach an auxiliary | assistant absorber to the back part of a disposable diaper, and to attach.

図１および図２はそれぞれ、本考案の一の実施の形態に係る使い捨ておむつ１の正面図および背面図（すなわち、着用者の腹側および背側に位置する部位の図）である。図１および図２に示すように、使い捨ておむつ１は、上端（すなわち、図１および図２中の上側の端部）に胴部開口１１を有し、下部に一対の脚部開口１２を有するパンツタイプの吸収性物品であり、着用者からの排泄物を受ける。図１および図２では、左右方向に伸張した状態の使い捨ておむつ１を示す（図６ないし図９においても同様）。 FIGS. 1 and 2 are a front view and a rear view, respectively, of a disposable diaper 1 according to an embodiment of the present invention (that is, a view of a portion located on the wearer's belly side and back side). As shown in FIGS. 1 and 2, the disposable diaper 1 has a trunk opening 11 at the upper end (that is, the upper end in FIGS. 1 and 2) and a pair of leg openings 12 at the lower part. A pants-type absorbent article that receives excrement from the wearer. 1 and 2 show the disposable diaper 1 in a state of being stretched in the left-right direction (the same applies to FIGS. 6 to 9).

図３は、使い捨ておむつ１を展開した状態で着用者側から見た平面図である。使い捨ておむつ１は、胴部開口１１および一対の脚部開口１２（図１および図２参照）を有する外装シート４、および、外装シート４の内面（すなわち、着用者側の面）上に取り付けられて着用者からの排泄物を吸収する略シート状の吸収体２０を備える。外装シート４は、外装シート本体４０、並びに、外装シート本体４０に伸張状態にて接合される脚部弾性部材４３、胴部弾性部材４４および中間弾性部材４５を備える。 Drawing 3 is a top view seen from a wearer side in the state where unfolded disposable diaper 1 was carried out. The disposable diaper 1 is mounted on an exterior sheet 4 having a trunk opening 11 and a pair of leg openings 12 (see FIGS. 1 and 2), and an inner surface (that is, a wearer-side surface) of the exterior sheet 4. A substantially sheet-like absorber 20 that absorbs excrement from the wearer. The exterior sheet 4 includes an exterior sheet body 40, and leg elastic members 43, body elastic members 44, and intermediate elastic members 45 that are joined to the exterior sheet body 40 in an expanded state.

使い捨ておむつ１では、図３中の下側の部位が着用者の前側（腹側の肌）を覆い、図３中の上側の部位が着用者の後側（背側の肌）を覆う。以下の説明では、外装シート本体４０の着用者の腹側および背側に位置する部位をそれぞれ、「前方部４０１」および「後方部４０３」と呼び、前方部４０１と後方部４０３との間で前方部４０１および後方部４０３から連続するとともに着用者の股間部を覆う部位を「股下部４０２」と呼ぶ。また、前方部４０１、股下部４０２および後方部４０３が並ぶ方向を「長手方向」という。使い捨ておむつ１では、外装シート４が前方部４０１、股下部４０２および後方部４０３を備え、吸収体２０は、外装シート４の前方部４０１から股下部４０２を経由して後方部４０３へと至る。外装シート４の前方部４０１、股下部４０２および後方部４０３は、使い捨ておむつ１の前方部、股下部および後方部でもある。 In the disposable diaper 1, the lower part in FIG. 3 covers the wearer's front side (abdominal skin), and the upper part in FIG. 3 covers the wearer's rear side (skin on the back side). In the following description, the portions of the exterior sheet main body 40 located on the abdomen side and the back side of the wearer are referred to as “front part 401” and “rear part 403”, respectively, and between the front part 401 and the rear part 403. A portion that continues from the front portion 401 and the rear portion 403 and covers the crotch portion of the wearer is referred to as a “crotch portion 402”. A direction in which the front portion 401, the crotch portion 402, and the rear portion 403 are arranged is referred to as a “longitudinal direction”. In the disposable diaper 1, the exterior sheet 4 includes a front part 401, a crotch part 402, and a rear part 403, and the absorbent body 20 reaches the rear part 403 from the front part 401 of the exterior sheet 4 via the crotch part 402. The front part 401, the crotch part 402, and the rear part 403 of the exterior sheet 4 are also a front part, a crotch part, and a rear part of the disposable diaper 1.

使い捨ておむつ１が製造される際には、外装シート４が吸収体２０と共に股下部４０２にて折り曲げられ、股下部４０２を下側に向けた際の前方部４０１の両側端部（すなわち、左右両側の端部）の内面と、後方部４０３の両側端部の内面とが、加熱および押圧による熱融着によりそれぞれ接続される。これにより、図１および図２に示すように、前方部４０１および後方部４０３の上端に胴部開口１１が形成され、前方部４０１および後方部４０３の下側において股下部４０２の左右に一対の脚部開口１２が形成される。 When the disposable diaper 1 is manufactured, the exterior sheet 4 is folded together with the absorbent body 20 at the crotch portion 402, and both end portions of the front portion 401 when the crotch portion 402 is directed downward (that is, both left and right sides). And the inner surfaces of both end portions of the rear portion 403 are connected to each other by heat fusion by heating and pressing. As a result, as shown in FIGS. 1 and 2, a trunk opening 11 is formed at the upper ends of the front part 401 and the rear part 403, and a pair of left and right crotch parts 402 is formed below the front part 401 and the rear part 403. A leg opening 12 is formed.

図４は、使い捨ておむつ１を図３中に示すＡ−Ａの位置にて切断した断面図である。図４は、使い捨ておむつ１の股下部４０２における断面を示す。図４では、図示の都合上、使い捨ておむつ１の各構成を離して描いている。図３および図４に示すように、吸収体２０は、略シート状の本体部２、および、本体部２の両側部上（すなわち、上下方向に垂直な左右方向の両側）に配置される一対のサイドシート３を備える。各サイドシート３は、本体部２の長手方向（すなわち、図３中の縦方向）のおよそ全長に亘って延びる。 FIG. 4 is a cross-sectional view of the disposable diaper 1 cut at the position AA shown in FIG. FIG. 4 shows a cross section of the crotch part 402 of the disposable diaper 1. In FIG. 4, for convenience of illustration, each component of the disposable diaper 1 is drawn separately. As shown in FIG. 3 and FIG. 4, the absorbent body 20 is a substantially sheet-shaped main body 2 and a pair disposed on both sides of the main body 2 (that is, on both sides in the left-right direction perpendicular to the vertical direction). Side sheet 3 is provided. Each side seat 3 extends over substantially the entire length in the longitudinal direction of the main body 2 (that is, the longitudinal direction in FIG. 3).

本体部２は、図４に示すように、トップシート２１、バックシート２３、および、トップシート２１とバックシート２３との間に配置された略シート状の吸収コア２２を備える。トップシート２１は、吸収コア２２の着用者側の主面を覆う。バックシート２３は、吸収コアの着用者とは反対側の主面を覆う。トップシート２１とバックシート２３とは、吸収コア２２の周囲にて互いに接合されて吸収コア２２を被覆する。 As shown in FIG. 4, the main body 2 includes a top sheet 21, a back sheet 23, and a substantially sheet-shaped absorbent core 22 disposed between the top sheet 21 and the back sheet 23. The top sheet 21 covers the main surface of the absorbent core 22 on the wearer side. The back sheet 23 covers the main surface opposite to the wearer of the absorbent core. The top sheet 21 and the back sheet 23 are joined to each other around the absorbent core 22 to cover the absorbent core 22.

トップシート２１は、透液性のシート材料であり、着用者からの排泄物の水分を速やかに捕捉して吸収コア２２へと移動させる。吸収コア２２は、着用者から排泄された尿等の液体を吸収する。バックシート２３は、排泄物の水分等が、本体部２の外側にしみ出すのを防止する。バックシート２３がホットメルト接着剤等にて外装シート４上に接合されることにより、吸収体２０の本体部２が外装シート４の内面上に取り付けられる。吸収体２０のバックシート２３は、全面に亘って外装シート４に接合されてもよく、部分的に接合されてもよい。 The top sheet 21 is a liquid-permeable sheet material that quickly captures the moisture of excrement from the wearer and moves it to the absorbent core 22. The absorption core 22 absorbs liquid such as urine excreted from the wearer. The backsheet 23 prevents excrement moisture and the like from oozing out of the main body 2. The main body 2 of the absorbent body 20 is attached on the inner surface of the exterior sheet 4 by bonding the back sheet 23 onto the exterior sheet 4 with a hot melt adhesive or the like. The back sheet 23 of the absorber 20 may be bonded to the exterior sheet 4 over the entire surface, or may be partially bonded.

トップシート２１としては、例えば、表面を界面活性剤により親水処理した疎水性繊維（ポリプロピレン、ポリエチレン、ポリエステル、ポリアミド、ナイロン等）にて形成された透液性の不織布（ポイントボンド不織布やエアスルー不織布、スパンボンド不織布等）が利用される。なお、トップシート２１として、セルロースやレーヨン、コットン等の親水性繊維により形成された不織布（例えば、スパンレース不織布）が利用されてもよい。 As the top sheet 21, for example, a liquid-permeable nonwoven fabric (point bond nonwoven fabric, air-through nonwoven fabric, etc.) formed of hydrophobic fibers (polypropylene, polyethylene, polyester, polyamide, nylon, etc.) whose surface is hydrophilically treated with a surfactant. Spunbond nonwoven fabric etc. are used. In addition, as the top sheet 21, a nonwoven fabric (for example, a spunlace nonwoven fabric) formed of hydrophilic fibers such as cellulose, rayon, or cotton may be used.

バックシート２３としては、疎水性繊維にて形成された撥水性または不透液性の不織布（例えば、スパンボンド不織布やメルトブロー不織布、ＳＭＳ（スパンボンド・メルトブロー・スパンボンド）不織布）や、撥水性または不透液性のプラスチックフィルムが利用される。バックシート２３にプラスチックフィルムが利用される場合、使い捨ておむつ１のムレを防止して着用者の快適性を向上するという観点からは、透湿性（通気性）を有するプラスチックフィルムが利用されることが好ましい。 As the back sheet 23, a water-repellent or liquid-impervious nonwoven fabric (for example, a spunbond nonwoven fabric, a meltblown nonwoven fabric, an SMS (spunbond / meltblown / spunbond) nonwoven fabric) formed of hydrophobic fibers, A liquid-impermeable plastic film is used. When a plastic film is used for the back sheet 23, a plastic film having moisture permeability (breathability) may be used from the viewpoint of preventing the disposable diaper 1 from being stuffy and improving the wearer's comfort. preferable.

図３に示すように、本体部２の長手方向の両端部における幅は、本体部２の長手方向の中央部（すなわち、股下部４０２と重なる部位）における幅よりも大きい。換言すれば、本体部２は、平面視においていわゆる砂時計型である。吸収コア２２は、平面視において略長方形であり、左右方向の幅は長手方向の全長に亘っておよそ一定である。以下の説明では、使い捨ておむつ１の各構成の左右方向の幅を単に「幅」といい、長手方向の長さを単に「長さ」という。吸収コア２２の幅は、吸収コア２２の全長に亘って本体部２の幅よりも小さい。図３では、図の理解を容易にするために、吸収コア２２の輪郭を太破線にて描いている（図１、図２、図６および図７においても同様）。また、図１および図２では、吸収体２０の輪郭を細実線にて描いている（図６ないし図９においても同様）。 As shown in FIG. 3, the width at both ends in the longitudinal direction of the main body 2 is larger than the width at the center in the longitudinal direction of the main body 2 (that is, the portion overlapping the crotch portion 402). In other words, the main body 2 has a so-called hourglass shape in plan view. The absorbent core 22 is substantially rectangular in plan view, and the width in the left-right direction is substantially constant over the entire length in the longitudinal direction. In the following description, the width in the left-right direction of each component of the disposable diaper 1 is simply referred to as “width”, and the length in the longitudinal direction is simply referred to as “length”. The width of the absorbent core 22 is smaller than the width of the main body 2 over the entire length of the absorbent core 22. In FIG. 3, the outline of the absorbent core 22 is drawn with a thick broken line in order to facilitate understanding of the drawing (the same applies to FIGS. 1, 2, 6, and 7). Moreover, in FIG. 1 and FIG. 2, the outline of the absorber 20 is drawn with the thin continuous line (the same also in FIG. 6 thru | or FIG. 9).

図４に示すように、吸収コア２２は、積層された２枚のシート部材である第１コアシート２２１および第２コアシート２２３と、第１コアシート２２１および第２コアシート２２３の間に保持される高吸収性材料２２２とを備える。第１コアシート２２１および第２コアシート２２３としては、トップシート２１と同様に、表面を界面活性剤により親水処理した疎水性繊維にて形成された透液性の不織布や、親水性繊維により形成された不織布が利用される。高吸収性材料２２２としては、例えば、粒状の高吸収性ポリマー（ＳＡＰ（Super Absorbent Polymer））や、繊維状の高吸収性ファイバー（ＳＡＦ（Super Absorbant Fibre））が利用される。本実施の形態では、粒状のＳＡＰが高吸収性材料２２２として利用される。また、吸収コア２２は、第１コアシート２２１と第２コアシート２２３との間に、粉砕されたパルプ繊維やセルロース繊維等、比較的嵩高な繊維を実質的に保持していない。 As shown in FIG. 4, the absorbent core 22 is held between a first core sheet 221 and a second core sheet 223 that are two stacked sheet members, and between the first core sheet 221 and the second core sheet 223. Superabsorbent material 222. As with the top sheet 21, the first core sheet 221 and the second core sheet 223 are formed of a liquid-permeable nonwoven fabric formed of hydrophobic fibers whose surfaces are hydrophilically treated with a surfactant, or hydrophilic fibers. A non-woven fabric is used. As the superabsorbent material 222, for example, a granular superabsorbent polymer (SAP (Super Absorbent Polymer)) or a fibrous superabsorbent fiber (SAF (Super Absorbant Fiber)) is used. In the present embodiment, granular SAP is used as the superabsorbent material 222. Further, the absorbent core 22 does not substantially hold relatively bulky fibers such as pulverized pulp fibers and cellulose fibers between the first core sheet 221 and the second core sheet 223.

高吸収性材料２２２は、ホットメルト接着剤等により第１コアシート２２１と第２コアシート２２３との間に接合される。高吸収性材料２２２は、第１コアシート２２１および第２コアシート２２３の外縁部を除く領域のおよそ全体に配置される。高吸収性材料２２２が配置される領域では、高吸収性材料２２２は略均一に分布する。このため、吸収体２０の厚さは、吸収コア２２の高吸収性材料２２２が存在する領域にて、左右方向において略均一である。 The superabsorbent material 222 is bonded between the first core sheet 221 and the second core sheet 223 by a hot melt adhesive or the like. The superabsorbent material 222 is disposed in almost the entire region excluding the outer edge portions of the first core sheet 221 and the second core sheet 223. In the region where the superabsorbent material 222 is disposed, the superabsorbent material 222 is distributed substantially uniformly. For this reason, the thickness of the absorber 20 is substantially uniform in the left-right direction in the region where the superabsorbent material 222 of the absorbent core 22 is present.

図４に示すように、一対のサイドシート３はそれぞれ、長手方向の全長に亘って設けられた折り曲げ線３９の一方側の部位である帯状の接合部３３と、折り曲げ線３９の他方側の部位である側壁部３４と、側壁部３４に接合される側壁部弾性部材３５とを備える。一対の接合部３３は、本体部２の左右方向の両側部において、本体部２の長手方向のおよそ全長に亘って配置される。各接合部３３は、本体部２の着用者側にホットメルト接着剤等を用いて接合される。一対の側壁部３４は、一対の接合部３３の左右方向の内側のエッジ（すなわち、折り曲げ線３９）にて一対の接合部３３から連続する部位であり、本体部２の左右方向の両側部上において本体部２の長手方向のおよそ全長に亘って延びる。 As shown in FIG. 4, each of the pair of side sheets 3 includes a band-shaped joint portion 33 that is a portion on one side of a fold line 39 provided over the entire length in the longitudinal direction, and a portion on the other side of the fold line 39.

Further, the color of the front mark portion 481 is different from the color of the rear mark portion 482.

前目印部４８１は、２本の中間弾性糸４５１ａのそれぞれに注目すると、左右方向に延びる略直線状であり、２本の中間弾性糸４５１ａおよび２本の中間弾性糸４５１ａの間の領域をまとめて、左右方向に延びる帯状と捉えることもできる。後目印部４８２も同様に、２本の中間弾性糸４５１ｂのそれぞれに注目すると、左右方向に延びる略直線状であり、２本の中間弾性糸４５１ｂおよび２本の中間弾性糸４５１ｂの間の領域をまとめて、左右方向に延びる帯状と捉えることもできる。 When attention is paid to each of the two intermediate elastic yarns 451a, the front mark portion 481 is a substantially straight line extending in the left-right direction, and the region between the two intermediate elastic yarns 451a and the two intermediate elastic yarns 451a is put together. Thus, it can also be regarded as a strip extending in the left-right direction. Similarly, when attention is paid to each of the two intermediate elastic yarns 451b, the rear mark portion 482 is substantially linear extending in the left-right direction, and is a region between the two intermediate elastic yarns 451b and the two intermediate elastic yarns 451b. Can be considered as a band extending in the left-right direction.

図６に示すように、前方部４０１では、前目印部４８１の上側の中間弾性糸４５１ａは、吸収体２０の前側の上端縁と胴部開口１１のエッジ１１１との間に位置し、下側の中間弾性糸４５１ａは、吸収体２０の前側の上端縁と吸収コア２２の上端縁との間に位置する。また、図７に示すように、後方部４０３では、後目印部４８２の２本の中間弾性糸４５１ｂは、吸収体２０の後側の上端縁と胴部開口１１のエッジ１１１との間に位置する。図６および図７に示すように、後目印部４８２は、前目印部４８１よりも上方に位置する。後目印部４８２と胴部開口１１のエッジ１１１との間の上下方向の距離は、前目印部４８１と胴部開口１１のエッジ１１１との間の上下方向の距離よりも小さい。 As shown in FIG. 6, in the front portion 401, the intermediate elastic yarn 451 a on the upper side of the front mark portion 481 is positioned between the upper end edge on the front side of the absorbent body 20 and the edge 111 of the trunk portion opening 11. The intermediate elastic yarn 451 a is located between the upper end edge on the front side of the absorbent body 20 and the upper end edge of the absorbent core 22. Further, as shown in FIG. 7, in the rear portion 403, the two intermediate elastic yarns 451 b of the rear mark portion 482 are positioned between the rear upper end edge of the absorbent body 20 and the edge 111 of the trunk portion opening 11. To do. As shown in FIGS. 6 and 7, the rear mark portion 482 is located above the front mark portion 481. The vertical distance between the rear mark portion 482 and the edge 111 of the trunk opening 11 is smaller than the vertical distance between the front mark portion 481 and the edge 111 of the trunk opening 11.

図８および図９に示す使い捨ておむつ１および補助吸収具９が着用者に装着される際には、まず、使い捨ておむつ１の一対の脚部開口１２に着用者の脚を挿入し、使い捨ておむつ１が着用者の足首や膝や大腿部等に位置している状態で、使い捨ておむつ１の内側に補助吸収具９が装着される。このとき、着用者または介護者は、胴部開口１１を介して使い捨ておむつ１の内側を見て、補助吸収具９の後端部（例えば、後端縁）を、使い捨ておむつ１の後方部４０３の後目印部４８２に合わせる。また、補助吸収具９の前端部（例えば、前端縁）を、使い捨ておむつ１の前方部４０１の前目印部４８１に合わせる。これにより、補助吸収具９を、使い捨ておむつ１の内側の所定の位置に容易に配置することができる。そして、使い捨ておむつ１を引っ張り上げて着用者に装着することにより、補助吸収具９も着用者に装着される。 When the disposable diaper 1 and the auxiliary absorbent 9 shown in FIGS. 8 and 9 are attached to the wearer, first, the wearer's legs are inserted into the pair of leg openings 12 of the disposable diaper 1, and the disposable diaper 1 Is placed on the inner side of the disposable diaper 1 in a state where it is located on the wearer's ankle, knee, thigh or the like. At this time, the wearer or caregiver looks at the inside of the disposable diaper 1 through the torso opening 11 and looks at the rear end portion (for example, the rear end edge) of the auxiliary absorbent 9 and the rear portion 403 of the disposable diaper 1. To the rear mark portion 482. Further, the front end portion (for example, the front end edge) of the auxiliary absorbent 9 is aligned with the front mark portion 481 of the front portion 401 of the disposable diaper 1. Thereby, the auxiliary | assistant absorber 9 can be easily arrange | positioned in the predetermined position inside the disposable diaper 1. FIG. And the auxiliary | assistant absorber 9 is also mounted | worn with a wearer by pulling up the disposable diaper 1 and mounting | wearing a wearer.

なお、補助吸収具９および使い捨ておむつ１の装着は、他の方法により行われてもよい。例えば、使い捨ておむつ１が着用者の足首や膝や大腿部等に位置している状態で、着用者の股間部に補助吸収具９が宛がわれ、補助吸収具９を着用者に押さえておいてもらい、介護者が使い捨ておむつ１を引っ張り上げて着用者に装着させてもよい。 The auxiliary absorbent 9 and the disposable diaper 1 may be attached by other methods. For example, in a state where the disposable diaper 1 is positioned on the wearer's ankle, knee, thigh, etc., the auxiliary absorbent 9 is applied to the wearer's crotch, and the auxiliary absorbent 9 is pressed against the wearer. The caregiver may pull the disposable diaper 1 and put it on the wearer.

上記いずれの装着方法においても、使い捨ておむつ１が着用者に装着される過程において補助吸収具９の位置が変化し、補助吸収具９の使い捨ておむつ１に対する相対位置が所定の位置からずれてしまう場合がある。この場合、介護者等が、補助吸収具９の後端部（すなわち、後側の上端部）を、使い捨ておむつ１の胴部開口１１を介して把持し、後方部４０３の胴周り部４８に設けられた後目印部４８２（すなわち、２本の中間弾性糸４５１ｂ）を位置決めの基準として、補助吸収具９の後端部を胴周り部４８を介して視認しつつ当該後端部の長手方向における位置、および、後端部の左右方向の傾きを調整する。より具体的には、補助吸収具９の略直線状の後端縁を、例えば２本の中間弾性糸４５１ｂの間、かつ、中間弾性糸４５１ｂに平行に配置することにより、補助吸収具９の後端部の位置決めが行われる。 In any of the above mounting methods, the position of the auxiliary absorbent 9 changes in the process of mounting the disposable diaper 1 on the wearer, and the relative position of the auxiliary absorbent 9 with respect to the disposable diaper 1 deviates from a predetermined position. There is. In this case, a caregiver or the like grasps the rear end portion (that is, the upper end portion on the rear side) of the auxiliary absorbent 9 through the trunk opening 11 of the disposable diaper 1 and puts it on the trunk periphery 48 of the rear portion 403. Using the rear mark portion 482 provided (that is, the two intermediate elastic yarns 451b) as a positioning reference, the longitudinal direction of the rear end portion is visually confirmed through the waist portion 48 while the rear end portion of the auxiliary absorbent 9 is visually recognized. And the inclination of the rear end portion in the left-right direction are adjusted. More specifically, by arranging the substantially linear rear end edge of the auxiliary absorbent 9 between, for example, the two intermediate elastic yarns 451b and in parallel with the intermediate elastic yarn 451b, The rear end is positioned.

また、介護者等は、補助吸収具９の前端部を、使い捨ておむつ１の胴部開口１１を介して把持し、前方部４０１の胴周り部４８に設けられた前目印部４８１（すなわち、２本の中間弾性糸４５１ａ）を位置決めの基準として、補助吸収具９の前端部を胴周り部４８を介して視認しつつ当該前端部の長手方向における位置、および、前端部の左右方向の傾きを調整する。より具体的には、補助吸収具９の略直線状の前端縁を、例えば２本の中間弾性糸４５１ａの間、かつ、中間弾性糸４５１ａに平行に配置することにより、補助吸収具９の前端部の位置決めが行われる。 Further, a caregiver or the like grasps the front end portion of the auxiliary absorbent 9 through the trunk opening 11 of the disposable diaper 1 and provides a front mark portion 481 (that is, 2) provided on the trunk periphery 48 of the front portion 401. Using the intermediate elastic yarn 451a) as a positioning reference, the position of the front end portion in the longitudinal direction and the inclination of the front end portion in the left-right direction can be determined while visually recognizing the front end portion of the auxiliary absorbent 9 through the waist portion 48. adjust. More specifically, the front end of the auxiliary absorbent 9 is arranged by arranging the substantially straight front end edge of the auxiliary absorbent 9 between, for example, two intermediate elastic yarns 451a and in parallel with the intermediate elastic yarn 451a. The part is positioned.

使い捨ておむつ１では、上述のように、後目印部４８２と胴部開口１１のエッジ１１１との間の上下方向の距離は、前目印部４８１と胴部開口１１のエッジ１１１との間の上下方向の距離よりも小さい。このため、補助吸収具９を着用者に装着する際に、前目印部４８１および後目印部４８２を利用して補助吸収具９の使い捨ておむつ１に対する位置決めを行うことにより、補助吸収具９を使い捨ておむつ１の後方部に偏らせて取り付けることを容易とすることができる。その結果、使い捨ておむつ１および補助吸収具９の着用者が仰向けになった状態で排尿が行われた場合であっても、使い捨ておむつ１の後方部へと異動した尿が、補助吸収具９から漏出することを抑制または防止することができる。 In the disposable diaper 1, as described above, the vertical distance between the rear mark portion 482 and the edge 111 of the trunk opening 11 is the vertical direction between the front mark portion 481 and the edge 111 of the trunk opening 11. Less than the distance. For this reason, when attaching the auxiliary | assistant absorber 9 to a wearer, the auxiliary | assistant absorber 9 is disposable by positioning with respect to the disposable diaper 1 of the auxiliary | assistant absorber 9 using the front mark part 481 and the back mark part 482. It can be made easy to be biased and attached to the rear part of the diaper 1. As a result, even if urination is performed in a state where the wearer of the disposable diaper 1 and the auxiliary absorbent device 9 is lying on the back, urine moved to the rear part of the disposable diaper 1 is removed from the auxiliary absorbent device 9. Leakage can be suppressed or prevented.

後目印部４８２は、吸収体２０の後側の上端縁と胴部開口１１のエッジ１１１との間に位置するため、補助吸収具９を着用者に装着する際に、補助吸収具９の後端縁を吸収体２０の後側の上端縁よりも上側に容易に位置させることができる。その結果、補助吸収具９を使い捨ておむつ１の後方部にさらに偏らせて取り付けることができる。また、前目印部４８１および後目印部４８２はそれぞれ、左右方向に延びる直線状または帯状である。これにより、補助吸収具９の位置決め、すなわち、後端縁および前端縁をそれぞれ前目印部４８１および後目印部４８２に合わせて補助吸収具９を配置することを容易とすることができる。 The rear mark portion 482 is located between the upper end edge on the rear side of the absorbent body 20 and the edge 111 of the trunk opening 11. Therefore, when the auxiliary absorbent device 9 is attached to the wearer, The edge can be easily positioned above the upper edge on the rear side of the absorbent body 20. As a result, the auxiliary absorbent 9 can be attached to the rear part of the disposable diaper 1 while being further biased. Each of the front mark portion 481 and the rear mark portion 482 has a linear shape or a belt shape extending in the left-right direction. Thereby, it is possible to easily position the auxiliary absorbent 9, that is, to arrange the auxiliary absorbent 9 with the rear end edge and the front end edge aligned with the front mark portion 481 and the rear mark portion 482, respectively.

使い捨ておむつ１では、前目印部４８１および後目印部４８２がそれぞれ中間弾性部材４５の一部であり、中間弾性部材４５の当該一部の色が、中間弾性部材４５の他の部位の色と異なる。このように、使い捨ておむつ１に元から設けられる構造を前目印部４８１および後目印部４８２として利用することにより、目印部として新たな部材を追加したり、目印部を印刷する必要がないため、使い捨ておむつ１の構造および製造を簡素化することができる。 In the disposable diaper 1, the front mark portion 481 and the rear mark portion 482 are each part of the intermediate elastic member 45, and the color of the part of the intermediate elastic member 45 is different from the color of other parts of the intermediate elastic member 45. . In this way, by using the structure originally provided in the disposable diaper 1 as the front mark part 481 and the rear mark part 482, it is not necessary to add a new member as the mark part or print the mark part. The structure and manufacture of the disposable diaper 1 can be simplified.

上述のように、前目印部４８１と後目印部４８２とが互いに異なる色を有する。このため、使い捨ておむつ１の前後の区別を容易につけることができる。その結果、使い捨ておむつ１の着用を容易とすることができる。使い捨ておむつ１では、後目印部４８２は、必ずしも前目印部４８１と異なる色を有する必要はなく、例えば、前目印部４８１と異なる形状を有していてもよい。具体的には、後目印部４８２の中間弾性糸４５１ｂとして、前目印部４８１の中間弾性糸４５１ａよりも太い弾性糸が利用されてもよい。あるいは、後目印部４８２に含まれる中間弾性糸４５１ｂの本数を、前目印部４８１に含まれる中間弾性糸４５１ａの本数と異ならせてもよい。また、後目印部４８２として、２本の中間弾性糸４５１ｂに代えて、左右方向に延びる略帯状の弾性部材が利用され、前目印部４８１の２本の中間弾性糸４５１ａと区別されてもよい。このように、後目印部４８２が前目印部４８１と異なる外見（色や形状等）を有することにより、使い捨ておむつ１の前後の区別を容易につけることができる。 As described above, the front mark portion 481 and the rear mark portion 482 have different colors. For this reason, the front and rear of the disposable diaper 1 can be easily distinguished. As a result, the disposable diaper 1 can be easily worn. In the disposable diaper 1, the rear mark portion 482 does not necessarily have a color different from that of the front mark portion 481. For example, the rear mark portion 482 may have a shape different from that of the front mark portion 481. Specifically, an elastic thread thicker than the intermediate elastic thread 451a of the front mark part 481 may be used as the intermediate elastic thread 451b of the rear mark part 482. Alternatively, the number of intermediate elastic yarns 451b included in the rear mark portion 482 may be different from the number of intermediate elastic yarns 451a included in the front mark portion 481. Further, as the rear mark portion 482, a substantially band-like elastic member extending in the left-right direction is used instead of the two intermediate elastic yarns 451b, and may be distinguished from the two intermediate elastic yarns 451a of the front mark portion 481. . As described above, the rear mark portion 482 has an appearance (color, shape, etc.) different from that of the front mark portion 481, so that the front and rear of the disposable diaper 1 can be easily distinguished.

上述の使い捨ておむつ１は、様々な変更が可能である。 The disposable diaper 1 described above can be variously changed.

例えば、外装シート４では、第２外装シート４２の上端が第１外装シート４１の上端とおよそ一致し、エンドシート５が第２外装シート４２の内面に接合されてもよい。この場合、中間弾性部材４５は、第１外装シート４１と第２外装シート４２との間、または、第２外装シート４２とエンドシート５との間に接合される。 For example, in the exterior sheet 4, the upper end of the second exterior sheet 42 may substantially coincide with the upper end of the first exterior sheet 41, and the end sheet 5 may be joined to the inner surface of the second exterior sheet 42. In this case, the intermediate elastic member 45 is joined between the first exterior sheet 41 and the second exterior sheet 42 or between the second exterior sheet 42 and the end sheet 5.

前目印部４８１および後目印部４８２である中間弾性糸４５１ａ，４５１ｂはそれぞれ、必ずしも胴周り部４８の胴周り方向のおよそ全周に亘って設けられる必要はなく、胴周り部４８の少なくとも一部に胴周り方向に沿って接合されていればよい。 The intermediate elastic yarns 451a and 451b that are the front mark portion 481 and the rear mark portion 482 are not necessarily provided over the entire circumference of the waist circumference direction of the waist circumference portion 48, and at least a part of the waist circumference portion 48. What is necessary is just to join to the trunk periphery direction.

前目印部４８１および後目印部４８２はそれぞれ、１本または３本以上の略直線状の中間弾性糸４５１であってもよく、波線状等、直線状以外の中間弾性糸であってもよい。また、前目印部４８１および後目印部４８２はそれぞれ、中間弾性部材４５として設けられる１本または複数の略帯状の弾性部材であってもよい。 Each of the front mark portion 481 and the rear mark portion 482 may be one or three or more substantially straight intermediate elastic yarns 451, or may be an intermediate elastic yarn other than a straight shape such as a wavy line. Each of the front mark portion 481 and the rear mark portion 482 may be one or a plurality of substantially band-shaped elastic members provided as the intermediate elastic member 45.

前目印部４８１および後目印部４８２は、必ずしも中間弾性部材４５の一部である必要はない。例えば、インクジェット印刷等により外装シート本体４０に印刷された直線や円等の図形が、前目印部４８１または後目印部４８２として利用されてもよい。また、外装シート本体４０と異なる有色のホットメルト接着剤が、第１外装シート４１と第２外装シート４２との間に線状や帯状等に塗布され、あるいは、有色の帯状の不織布等が第１外装シート４１と第２外装シート４２との間に接合され、当該ホットメルト接着剤や有色部材が前目印部４８１または後目印部４８２として利用されてもよい。 The front mark portion 481 and the rear mark portion 482 are not necessarily part of the intermediate elastic member 45. For example, a figure such as a straight line or a circle printed on the exterior sheet main body 40 by inkjet printing or the like may be used as the front mark portion 481 or the rear mark portion 482. Also, a colored hot-melt adhesive different from the exterior sheet main body 40 is applied in a line shape or a strip shape between the first exterior sheet 41 and the second exterior sheet 42, or a colored strip-shaped nonwoven fabric or the like is applied. The first exterior sheet 41 and the second exterior sheet 42 are bonded to each other, and the hot melt adhesive or the colored member may be used as the front mark part 481 or the rear mark part 482.
